What can I do if my LCD screen seems faint?

If you are operating your handheld in low light conditions, try using the backlighting feature.
While the handheld is on, press the power key to activate backlighting. Backlighting turns off
after ten seconds if you do not press a key or use the trackwheel. You can turn off the
backlighting manually by pressing the power key again.
The handheld backlighting turns on automatically when you receive an incoming phone call.
If your screen seems faint all the time, check the Screen/Keyboard option on the Options screen.
Refer to "Screen/Keyboard" on page 228 for more information on setting these fields.
Maintenance

I accidentally dropped my handheld in water and now it does not work. What should I

do?

While a few drops of moisture should not damage your handheld, you should avoid placing it in
direct contact with liquids. If your handheld is exposed to liquid and stops operating, let it dry out
completely, allowing time for internal components to dry. If it does not begin to work again when
it is dry, contact your service provider or network operator.

How can I reset my handheld?

On rare occasions, the handheld might report an internal handheld error message, and instruct
you to press R to reset. You can also reset the handheld by pressing ALT + SHIFT + BACKSPACE.
A reset hole is located on the back of the handheld. If your handheld no longer responds when
you press keys or use the trackwheel, insert one end of a paper clip into this hole to press the
reset button. Your handheld restarts and should return to normal operation.
